TANK CAB.

Application filed October 16, 1920. Serial No. 417,353.

To 'all whom. t mag/,concern Be it known that I, WILLIAM K. AUCHIN- GLOSS, residing at New York, in the county and State of New York, and being a citizen of the United States, have invented certain new and useful improvements in a Tank Car, of which the ollowin is a full, clear, and exact description, suci as-will enable others skilled in the art'to which it -apertains to make and use the same, reference being had to the accompanying drawings, which illustrate the preferred lform of the invention,- though it is to bel understood that the invention is not limited to the exact details of construction shown and described, as it is obv1cus that various modifications' thereof within the scope of the claims will 'in means use in connection therewith; and

igure 4 is an enlarged view of a portion of Flg. 2 showing the respective positions ofthe retaining straps and insulating blocks of my invention.

insulated car tanks as' previously ,con-

structed have been provided with a layer of, a light heat insulating material placed between the inner and outer tanks and it has been found in practice that this light material does not possess` suiiicient resistance to prevent deformation of the lighter outer tank by the pressure exertedl thereon in service by the tank bands that secure the I tank to' the car frame. 1t is therefore, the

object' of vmy invention to provide a means wherebyV the tank bands will be prevented from deforming the outer tank or protective sheathing and to this end it comprises blocks of a suitable heat insulating material secured to the. inner tank andl serving to support the outer (ank where subjected to the pressure to the tank bands.

n the drawing, 1 designatesan insulated 'car tank comprising an inner tank 2 and an outer or rotecting tank or sheathing 3 of lighter p ates separated from theinner tank 2 by' a layer of suitable heat insulating material 4, as hair felt or similar material, the sections of the outer ltank being provided with slip joints 5 that permit of the nuten tank being drawn tightly against the insula-i tion. v

As shown in Fig. l, the inner tank 1 rests upon the :saddle blocks 6 carried bythe car underframe 7 and is secured in position by the tank ha 'ds 8A which extend over the outer` tank and tirough openings vin the bolsterH members ,9J Nuts 1Q secure the tank bands 8 in positie The bottom sheets of the outer tank extend beneath the inner tank 4to the correspending; slip joints 5 (not shown) on the other side except at the bolsters, wherethey are cut away so as to per-mit the .inner tank to rest u dn the saddle blocksf and at the tank ancy oring meanswhere the outer tank sheets are also secured to the tank anchoring means. L

The insulation beneath those portions of' the outeir tank that are subjected to the pressure pfthe tank bands 8 is replaced by an insulation that will retain its shape when subjectedi to the pressure of the band as the Iblocks ill of wood or other suitable i heat insulating material. The blocks 1l are cutso lthat when ,itted together they will form a portion of a ring that will enga e the outer surface of the inner tank 2 'an extend between'the angle bar members 12, only one of which is shown in the drawings, riveted or otherwise secured to the outer surface of the inner tank 2. rlhe blocks 11 have a slot'in their outer surfaces and are held in plafie by a tie rod 13 which lies in the slot and ihas its ends extending through openings in the angle bars 12. Nuts 14 screwed on the ends of the tie rod 13 hold the' tie rod in position. To position the nuts 1A behind the surface plane oi the blocks, theslotsin theend blocksl deepen gradually as ihey approach the angle bar members..l

As shown 'inthe drawings, but a single tie rod 13 placed in. av slot ,directly under the band 8 is used but a plurality of tie rods 13 placed in sl maybe usedV i What I claim is:

l. .In a tank car, a tank, a sheathing for said. tank, yielding 'and ,unyielding insnlation between said, tank` and sheathing` and. bands secnringgsaid tankand slleathinsr to.

`pts on each side.oit the band 8 A the ear frame, said unyielding insulation preventing deformation of by said bands.

2. In an insulated tank car, inner and outer tanks, bands securing said tank te the said sheathing carframe and insulation between said tanks adllgiwted to prevent deformationof said outer ta by said bands.

3. In an insulated. tank car, inner and outer tanks; bands securing said tanks to the fcar frame, insulation'b'etwee'n said tanks and linsulating lblocks separating; said tanks and reventing .deformation of said outer tank y saidbands. l

4. In an'insulated tank `vcar, inner and outer tanksfbands securing);v said tanks te the car frame, insulating blocks between said ta'nks and means hqldingsaidbloks in v, psitienagainst/ one of the tanks, said blocks 2o Router tanks, bands securing said tanks to the 'car frame, angle bar members secured to said inner tank, insulating blocks -between said 6. In a tank cai, a tank, angles secured tot` said tank, groei-fed insulating blocks carried by said tank and a rod {itt-ing the groove 1n said blocks'and having its ends secured to said angles to secure said blocksto said tank.

'4'. In a tank car,v an underframe, a tank carried by said underframe, a sheathingif for saiditank, gi'ooved insulating blocks between said tank and' sheathing, a rod fitting the groove inv said blocks and seoui'ing said blocks to rthe tank and' a band securing said tank and sheathing to said undei'franiesaid blocks transmitting the pressure :from said band to said tank. y

n Witness whereof have hereunto set my hand .in the presence of two Witnesses.
